Patch 5.0.4 (28-August-2012): Re-added; changed from All party or raid members within 45 yards of the Death Knight move X% faster. This effect does not stack with other movement improving effects.

Patch 3.1.0 (14-Apr-2009): Replaced with Improved Unholy Presence. Allows the death knight to keep the movement speed bonus of Unholy Presence in any presence, and increases rune regeneration rate while in Unholy Presence.
